Please help ~~~ 4 1091
Hi,
If drInvChg.Item("exrate") is expecting a string then do this:
drInvChg.Item("exrate") = "1.0"
Or if (drInvChg.Item() takes an integer for an argument instead of a string
(i.e. "exrate") then you'll need to supply an integer. Right now my guess
is the 2nd one because you can assign 1.0 to a string variable, but the
string will contain "1" instead of "1.0". Good luck! Ken.

drInvChg.item("exrate") is the exchange rate , it must be decmial , not a
string. I am wonder why there is an error

Hi,
Could you post more code. What is drInvChg? A datarow? Also what is
drInvInfo? What type of objects are these? I would put a breakpoint on
your For Each line. Then highlight drInvChg.Item("exrate") and put it in
your watch window. What type of value does it return? A String? You are
getting this error because one of your values is a string that can not be
converted to a double data type. Good luck! Ken.
